Just saying that the efficiency is probably less doesn't make it true.
As far as I can tell its a trade up between...
gasoline refining + transport to filling station + losses in internal combustion engine
versus
burn in power station (more efficient that small scale internal combustion engine) + transmission losses (6.5% from wikipedia) + losses in electric motors (less than internal combustion engine) ...so I disagree.
